– Coral reefs threatened by overfishing, tourism, and CO2 emissions
– Oil spills contribute to marine pollution
– Shipping introduces exotic marine species and harms whale populations

**Threats to Marine Life:**
– Overfishing decreases oceans’ wildlife population
– Invasive species disrupt ecosystem balance and lead to species demise
– Endangered species like sea turtles and Pacific bluefin tuna face population declines
– Marine plants like Johnsons seagrass are declining due to various factors
Human activities threaten coral reefs, critical biodiversity hotspots

**Conservation Techniques and Efforts:**
– Strategies include marine protected areas and sustainable fisheries

Conservation organizations like Ocean Conservancy and Greenpeace leading advocacy efforts
– International agreements and organizations supporting marine conservation
– Ocean conservation initiatives utilizing technology and public awareness campaigns

Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions and focuses on limiting human-caused damage to marine ecosystems, restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change.

Coral reefs have a great amount of biodiversity.

Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors, such as demand for marine resources, maritime law, economics, and policy, in order to determine how to best protect and conserve marine species and ecosystems. Marine conservation may be described as a sub-discipline of conservation biology.
